The radar on NASA and JAXA's Tropical Rainfall Measuring Mission (TRMM) satellite saw Typhoon Usagi maintaining some of its inner-core structure an hour before landfall on Sept. 22, 2013. The data was used to create an image that showed the 3-D regions of heavy precipitation hiding under the circular cloud cover near Usagi's center of rotation.
